Hey guys, I have a Eanon PX30 with the hal9k mod. I recently tried to add a sub and amp and I don't seem to be getting any signal at all from the RCA output. Any idea what I might have done wrong? Amp has power and everything else looks like it's hooked up right. Is there a setting i need to turn on? Any advice would be greatly appreciated.

Hello
I've searched and tried plenty, and maybe this was covered but I can't find anything..
I recently bought a Klyde unit for my 2013 Hyundai sonata with dimension stereo and stock amplifier..
The wiring seemed simple enough, but I cannot get any sound through my speakers.
I did quite a bit of troubleshooting and even got a replacement canbus decoder from the seller but still nothing..
Is there a simple solution that someone else knows or should I just return the thing and get a different one..
Thanks a million I'm stumped
Edit: the rca cables have sound coming out but I'm trying to keep the stock amplifier and speakers..
The spdif signal going to the canbus "amp controller" box gets 12v power, I get about 200 to 250mv signal into it but 10mv going out to the car's harness
Is there a way to "enable" the amp controller like the Metra boxes?
Sent from my SM-N900W8
Anyone?
I have more pics if it helps
Thanks again
Bought a Metra amp interface and now it works
I am wondering if this might be how to solve my problem. This is the post I made on the large android head unit thread, do you think this metra amp interface would solve this for my lancer also?
if so which did you get and where, I think you have the same head unit I have.
"I just received my unit thursday I had it installed friday, but it was not giving any audio signal and the amp wasn't being turned on. They tried to manually turn on the amp, but there was still no audio coming through.
so I am wondering if there is anything I can do to troubleshoot it myself while waiting for a reply from the seller. There is a few notable things that might be the problem but I figured I would ask here to check before I start.
First there is a red wire that looks like it was cut right near the canbus unit it came this way out of the box, the installer said it had power to it, I am wondering if it's supposed to be cut or if reconnecting it could help, also there is a blue wire on the harness that is not connected into the harness also. will attach pictures. (or not because I am not allowed hopefully you can figure out how to see them below...)

blue wire ------- pasteboard dot co/MO6kqKs.jpg

So what Metra Interface Kit...
I know this is an old thread but I have a 2014 Sonata Limited w/ Dimension Amp and android head unit doesn't output audio either with the Amp controller box or spdif box. I believe these boxes that came with it are not working properly. Please inform me of what kit I need to purchase.
Seeing reports...
I'm seeing reports the the hybl-04 is the Metra kit that you have ended up using. Is this correct?
Hi guys,
I've got a monoblock amp for my sub and a 4 channel amp for my front components and rear coax's, however i'm yet to put them in and the car is running factory, other than my seicane px3 7.1.2 head unit (seat ibiza). I've noticed that the volume isn't exactly loud, even at 30 (max) it doesn't really distort the speakers, whereas i'd expect it to, just like the factory radio did. I'm concerned there is some kind of limit to the sound, or the processing is poor perhaps, and wondering will this transfer to my amps giving me low volume sound? Another thing i've noticed is aux input via the AUX rca input, is even quiter still when compared to USB / bluetooth audio, any reason?
The single rca sub pre - out, do these work, along with the equalizer sub setting?
After doing some reading i'm wondering if the likes of viper4android or Arise apps would be a solution to remove and limits to sound, although i've found no info on rooting or if there is a custom rom for this unit, px3, rk30sdk. Is it easy to back up the standard settings/firmware in case of anything going wrong, or not so easy? The MCU version is 'MTCD_MX_V2.59_1'
thanks
Same problem here, also with the Seicane px3 unit with 7.1.2.

damn it thats annoying.. so it's probably a common fault. My big concern is that its not hardware, but software so it'll just make the amp i hook up to it quiet also..
anyone able to shed light? is viper4audio a solution?
I also think it is software. Searched for volume mods but can't find them.

do you also have issues with bluetooth audio quality via a2dp app? and have you found a way to root it or get a custom rom on?

A2dp/Bluetooth works fine but I don't use it. No root yet and I didn't try a custom Rom.
I can still use the original radio and Bluetooth together with the Android system. Works great.
Hello,
I have a PX3 with android 7.1.2 with an abnormally low volume, however, when using the DVD this volume increases a lot, it seems that the volume of android was limited by software.
I'm trying to increase this volume, but without success right now.
Greetings.
Read today in another post to set the original radio from normal to 'boost'. It significantly raised the volume from the headunit.

That sounds good. Can you tell us where the post / mod is? I can't find it ...
Thank you!
It's no mod. Read it in a forum about Mercedes radio's (Audio20). The headunit is on the AUX from the original radio so the 'boost' setting on the original radio increases the volume for AUX.
I am unable to find the post you are talking about. The procedure is to enter the factory options (126) and raise the AUX volume in the "voice" menu?
Thanks.

No, it's not in the Android headunit! In my car the original radio/system from Mercedes is still there. So, I have two systems connected. The Android headunit is for the sound connected with the AUX from the original radio. In there I can set the volume of AUX to 'boost'.
It's this system: https://www.seicane.com/android-hd-...hd-1080p-video-steering-wheel-control-s018848
Hi all,
New member but long time observer.
I’m finally dipping my toe into the Android Headunit waters, and will use this as a log of what I get up to as well as the many questions I will have due to finding it quite difficult to source specific info on a good-sounding setup in my generation of VW Polo (6C).
My setup will initially entail a current VW-specific Joying HU running the intel chip, Android 8, and 4gb of ram, all the while using the supplied cabling to connect to the factory speaker and CANBUS looms.
I’ve chosen this HU because of its SPDIF output, and will eventually run it to a converter so I can output an optical signal to a Audison amplifier for the best possible signal.
From there I will use the amp to run a set of Morel front splits and rear coax.
I have a Focal sub, but another dedicated amp and enclosure will be required. So this will happen later.
So for now I’ll install the Morel splits and HU, and progress from there. .
My first question: whats the most responsive OBD2 transmitter that you would recommend to use with this HU?
And does anyone know what the new gen Joying HU RCA voltage is?
Cheers in advance!
From what I have read Joying is having issues with OBD2 on the new HU's. They are working on it and are going to come out with new firmware.
If you are using the SPDIF output then the voltage on the RCA doesn't matter, but it's pretty low. If you have even a somewhat ok amp then it won't matter much. Even crappy amps can handle low voltage from the RCA's.

Good to know re the firmware, but if it’s being fixed, then I’ll persist in finding a good OBD2 transmitter.
And yep, I’m aware the RCA’s won’t be used if I can use the SPDIF output, but I’m preparing just in case.
Hey all,
Does anyone know how to make the factory reverse camera work with the new Joying units?
Is it simply a case of splicing the cable from the rear camera and soldering on an RCA plug?
Cheers!

Hi Everyone,
As the title states, Has anyone got their 8227L working with a USB DAC? This head unit is not doing my poor Focal PS165's any justice, they deserve better sound quality! I've been trying to get my unit to work with a Behringer UCA202 USB DAC and I'm not having any luck. The unit is running a precompiled rooted rom from maybe march 2020? I found it on 4PDA. I've tried changing the USB settings to sound output in developer options. That did nothing. The unit won't automatically recognise the the DAC. I'm not even sure this is totally doable getting the DAC to play nicely with the MCU.
Any info is greatly appreciated!
Hi guys,
I installed my Junsun headunit recently(8g/128gb) to my 2015 Mitsubishi Outlander with Rockford amp(however it was not written on the oem head unit, but I have the Rockford sub speaker in the trunk). I love nee head unit, but have some issues. The most annoying is the sound quality, the music is a bit messy and I just can't make it right. Also I found that only the right channel works( so I had to set Spotify to mono than I can hear all the music...) Also there is a setup menu for balance, but it doesn't work at all. Also the image quality of the oem reverse camera is much worse and lagging a bit. Thanks for your tips
How is the amp connected to audio signal? Maybe you can provide some photos. Additionally you should try to get the pinout diagram of your original OEM radio. This helps to check if the wiring is correct. Maybe you can find it here: https://pinoutguide.com/dev/Mitsubishi/Outlander/

Hello it is connected through canbus. I suppsoe it is not the right version I need. Thanks for the pinout diagram I try to compare with my cables
If you Google a bit you will find many forums discussing the Rockford topic. There are special adapters and on Aliexpress you can find special can boxes which can be used if Rockford amp is in place. My assumption is you don't have the correct wiring harness/can box.
